v R. WHITAKER, JR.,V ET AL FEEDING MECHANISM Filed March 7, 1922 2 Sheats-Shee 2 @y MM5/W 15 of the feeder when the latter is in its bolt delivering position, so that the bolts which are vproperly caught upin the groove 16 by thefeeder during its upward 'movement slide down the surface 15 onto the surface 20 andy intothe trimming machine- To prevent the b olts...,from jumping outof the.

groove 17 a bifurcated guard 21 is provided. In order that the bolts may be delivered into the groove 17 of the chute 18 sol that the bolt heads will pass under the guard 21 it is necessary that the bolt' head-s rest upon thevupper edges 15 of the feeder and that the i'Shanks of ,the bolts project into the groove 16. Itis obvious, however, with the bolts lyingin the hopper in topsy turvy positions, that when the groove 16 has emergedfromythe mass of bolts the bolts will be on the feeder in various positions. Sometimes oneor more bolts will be properly positioned with the heads resting on the edges l5 and the Shanks projecting into the grooveg 16. Sometimes'one or more'bolts will be solcaught'up that the heads will'V be partly in' the groove and the shanks pro- 'jecting therefrom. And some-times one or mbrelbolts Will restentirely on the upper edges 15, not infrequently extending transversely across the edges. When the bolts assume this latter position andslide down onto the chute they impede the passage of Atheybolts which are properly positioned in groove. This condition often lasts dur- 'ing several reciprocations of the feeder, duringjjwhich time the bolts in thechute have m' been delivered into the trimming machine,

' tion'.

iand period theoperating parts of the "trimmer come together with no bolt between i'themfgthereby causing unnecessary wear on ftheftrirnmers or other parts which operate lon the boltsor other articles.

liiuorderjto insure that all the bolts or :O tlieffe'eder beforezthey slide down onto the r articles will be'in proper position on chute,"the'ffeedingfmechanism of the presehtfjinveritionjis.provided with means for removing `fromfdthe feeder all improperly 'positione'dlbolts or other articles. This is accomplished f imparting to the bolt carryingpart a 4vibratory movement as the feeder is rising into bolt deliveringl posi- The" vibrationy of the bolt carrying part of the feeder causes all bolts o r other articles, whose heads are not on the edges `15"'vvith their shanks projecting into the groove 16, to be thrown off the feeder and back into the hopper. The vibration is caused by imparting a lateral movement to the bolt carrying part of the feeder. To permit the bolt carrying part 23 to vibrate (this part comprising the edges 15 and the groove 16), it is hinged to the body part 24 of the feeder by means of lugs25 which are received in "correspondingrecesses 26 in the body part. A rod 27 loosely connects the bolt carrying part 23 with the body part 24. Secured to a projection rising from therear end of the boltuc'arrying part of thev feederV `is a pin-29 which, when the feeder rises and falls, travels in a cam path reaches its bolt deliveringposition. At the point in rthe doublebendy *where the greatest Wear'comes a wear plate 35'is' provided. ln order that no bolts may fall into the cam path 80, the rear end of the bolt carrying part of the feeder is provided with i a 'uard 36. y

y providing the feeding mechanism with an article carrying part to which a lateral vibration or other movement is imparted,

different andi distinct from the movement I whichb'ring" the articlesinto delivery position, all `articles which 'arev not properly positioned onfthe article carrying part are displaced and thrown back into the hopper,

and the `resultis that' there is unbroken and uninterrupted series of articles passing from the hopper down-the chute and into `the machine with which the feeding mechanism is connected. 7 f

Having thus described the invention what 1 we claim as new is l 1. A feeding mechanism comprising hopper, a vertically `reciprocating feeder, means for actuatingv the-feeder, and means for vibrating the article carrying part-of the feeder during its reciprocating movements.

2. A feeding mechanism comprising-a hopper,a pivoted feeder arranged to pass tuating the feeder, said'feeder having arelatively movable part for carrying articles lifted out ofthe hopper, and means fervi- 'through a slot in the hopper, means for acl brating the relatively movable part of the feeder. f

3. A feeding mechanism `comprising a hopper, a feeder arranged to risevertically through the hopper, means for actuating the feeder, said feeder having a relatively movable article carrying-parma cam path, and connections between the relatively movable part of the feeder and the cam pathfor imparting a vibratory movement tothe former.

4. AA feeding mechanism comprising a hopper, a vfeederadapted to rise `throughthe hopper to take up articles contained therein, means yfor actuating the feeder, said feeder having a grooved article carrying part hinged to the body part of the feeder, and means forvibrating the grooved article carrying part to displace 0r throw olf improperly positioned articles.

5. In a feeding mechanism comprising a hopper, a feeder adapted to rise through the hopper to take up articles contained therein and means for actuating the feeder, an article carrying part for said feeder relatively movable therewith, and means for vibrating said relatively movable part to displace or throw 0H any improperly positioned articles.

6. In a feeding mechanism comprising a hopper, a pivotally mounted feeder adapted to rise through the hopper to take up articles contained therein and means for actuating the feeder, an article carrying part for said feeder pivotally connected With `the feeder, a cam path having a double bend portion, and a pin connected With the article carrying part of the feeder and arranged to travel in the cam path.
